Planetary Ball Grinder

FenixES Planetary Ball Grinder

Planetary Ball Mills are suitable for grinding(dry\wet) and mixing some soft,hard,brittle and fibrous samples ,which are used wherever the highest degree of fineness as customer required,as well as the grinding result is repeatable.Apart from the classical mixing and size reduction processes,the mills also meet all the technical requirements for colloidal grinding.



Application field

  • Engineering / Electronics, Building materials, Agriculture,Medicine, Chemical/Syntheticmaterials,Geology/Metallurgy,Environment/Resource recovery,Glass/Ceramics, Biology

Sample type

  • Soft,Hard,Brittle ,Fibrous

Working Principle

When the planetary ball mill starts, the motor drives the common sun wheel to move, while the grinding jars, which are located on the sun wheel, turning around its own axis. The direction of the movement of the sun wheel is opposite to that of the grinding jars in the ration 1:-2.The grinding balls in the grinding jars are subjected to superimposed rotational movement, the so-called Coriolis forces.

Under this interaction, the grinding balls release high dynamic energies. The samples are constantly impacted by the grinding balls, and rapid crushed by the friction of the grinding jar’s inner wall at the same time.



  • Powerful and quick grinding down to nano fineness
  • Suitable for long-term and continuous operation
  • Reproducible results due to program grinding parameters
  • Grinding chamber automatic ventilation system for cooling the grinding jar
  • Grinding jars have 6 kinds of material ,the volume various from 12ml-500ml
  • Automatic direction reversal to avoid agglomerations
  • With 4 grinding platforms can process 2,4,8 samples simultaneously (BM40)
  • Speed ratio is customizable


Comfortable operation and easy cleaning

  • Efficient, maintenance-free drive is used for planetary ball mill, so as to guarantee the machine can maintain constant speed in continuous operation for a long time or under maximum overload. During the grinding, built-in high-power fans can automatically provide effective cooling for motors.
  • The planetary ball mill is designed by ergonomics, which integrates comfort and safety in operation.
  • The intelligent security lock ensures the safety of the instrument operating.
  • The humanized program design can set the grinding time, and can operate without the need of
  • personnel monitoring.






Grinding jar’s feature

  • The jar’s capacity and material are marked on the grinding jars ,which is easy to distinguish from others.
  • Wide kinds of materials to meet different treatment requirements
  • The O-ring can guarantee the dust -prevention
  • It’s easy to open the jars by the gap, which exacts between the grinding jars and lids
  • Grinding jars of agate, sintered aluminum oxide, zirconium oxide and tungsten carbide are coated with stainless steel jacket
  • Easy and safe to operating
